Application July 16, 1956, Serial No. 598,056

1 Claim. (Cl. 81-15) This invention relates to jaws for multiple grippliers or the like.

It is an object of the present invention to provide jaws for multiplegrip pliers which are removable and are made with various radii wherebyto adapt the same to various sizes of hose ferrules.

It is another object of the present invention to provide jaws formultiple grip pliers of the above type which are designed for crimpinghose ferrules for various sizes of hose and wherein the jaws can be usedin multiple grip type pliers, bench vises or with a hammer.

Other objects of the invention are to provide jaws for multiple grippliers bearing the above objects in mind which are of simpleconstruction, have a minimum number of parts, are inexpensive tomanufacture and eificient in operation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing, in which:

Figure 1 is a side 'elevational view of a preferred embodiment of thepresent invention shown in operative use;

Fig. 2 is a transverse sectional view taken along the line 22 of Fig. 1,and

Fig. 3 is a perspective view shown alone of one of the aws.

Referring now more in detail to the drawing, indicates generally amultiple grip pliers including the jaw 11 and the arcuate jaw 12pivota'lly connected to the jaw 11 by means of the pin 13, substantiallyas illustrated. The multiple pliers 10 also includes the actuating lever14 pivotally connected to the jaw 12 by means of the pin 15, the lever14 being connected to the jaw 10 by means of the pivotally mountedexternally threaded studs 16 and 17 and the internally threadedconnecting sleeve 18, in a manner well known to those skilled in theart.

In the practice of my invention, the jaws 11 and 12 are provided withthe cooperating straight edges 19 and 20 these portions of the jawsbeing hollow and of substantially U-shaped cross section (Fig. 2) for apurpose which will hereinafter become clear.

In the practice of my invention a pair of replaceable jaws are providedindicated generally at 21. Each of the jaws 21 is identical inconstruction and therefore only one will be described in detail.

Each jaw 21 includes a solid rectangular block 22 adapted to bepositioned against the straight edges 19 and 20 of the jaws 11 and 12,respectively. The outer side of each of the blocks 22 is integrallyformed with a reduced extension 23 forming with the block 22 a shoulder24, the extension 23 having the inclined edge 25 and being adapted tofit within the jaws 11 and 12 With the shoulder 24 abutting the inneredges of the jaws (Fig. 2). Each of the extensions 23 is provided with"ice a transverse mounting opening 26 which is adapted to be alignedwith corresponding openings provided in the opposite sides of the jaws11 and 12, and through which is received the mounting pin 27.

The inner face of each of the blocks 22 is provided with thesemicircular cutout 28 having a central transverse extension or groove29.

As shown in phantom in Fig. 1, when the lever 14 is drawn towards thehandle of jaw 11, the jaw 12 will move towards the jaw 11 about the axisof the pin 13 to bring the blocks 22 together to crimp a hose ferruletherebetween. Interchangeable pairs of replaceable jaws 21 will beprovided with various radii to fit different size hose ferrules. Thejaws can be used in the multiple grip type pliers shown, or bench visesor with a hammer for the same purpose. The pins 27 are removable topermit the replacement of the jaws, as will be obvious.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

What I claim as new and desire to protect by Letters Patent of theUnited States is:

The combination with a multiple grip pliers having a first jaw andhandle, a second jaw of arcuate shape pivotally connected to said firstjaw, an actuating lever pivotally connected to said second jaw and linkmeans pivotally connecting the handle of said first jaw and saidactuating lever together, of a pair of crimping jaws removably mountedin said first and second jaws, each of said crimping jaws comprising asolid block having a planer outer face, each of said first and secondjaws having straight edges adapted to abut said planer face, means forremovably mounting said blocks against said straight edges, each of saidblocks on the inner faces thereof having substantially semicircularcutouts adapted to cooperate to crimp a hose ferrule therebetween whensaid first and second jaws are closed, each of said cutouts at the innercentral portion thereof having a lateral groove, said means forremovably mounting said blocks comprising said first and second jawsbeing of substantially U-shaped cross section with open ends extendinginwardly, each of said blocks on said planer face being integrallyformed with a reduced extension forming with said block a pair ofshoulders, each of said extensions fitting between the open ends of saidjaws with said shoulders abutting said straight edges, each of saidextensions having a mounting opening extending transverselytherethrough, each of said first and second jaws having laterallyaligned openings in the ends thereof and aligned with said mountingopening, and removable pin means within said aligned openings whereby tosecurely mount said blocks on the straight edges of said first andsecond jaws for permitting their easy and ready removal for replacementwith other blocks having cutouts of varying radii whereby to adapt thedevice for use with hose ferrules of varying size.
